The Feast of the Holy Cross, Feast of the Exaltation of the Holy Cross, or Feast of the Cross commemorates the True Cross. On 13 September 335, the Constantinian Basilica over the Holy Sepulchre was consecrated in Jerusalem. The day after the church's consecration, the relic of the cross was shown ("exalted") for the first time to the people for veneration. Later, the feast was also associated with the commemoration of the recovery of the Holy Cross by the Byzantine emperor Heraclius on 13 September 628.
In the liturgical year, there are several celebrations which honor and celebrate the cross used in the crucifixion. Unlike Good Friday, which is dedicated to the passion of Christ and the crucifixion, these feast days celebrate the Cross itself, as the sign of salvation. It is celebrated by Catholics (Latin Church Catholics, Eastern Catholics), Eastern Orthodox, Oriental Orthodox, Church of the East, Old Catholics, Lutherans and Anglicans, and to a lesser extent by Presbyterians, Methodists and Baptists. The most common day of commemoration is September 14 for churches that use the Gregorian calendar and September 27 for churches that use the Julian calendar, Ge'ez calendar, or Coptic calendar.
In English, the feast is called the Feast of the Exaltation of the Holy Cross in the translation of the Roman Missal of 2010, while the 1973 translation called it Feast of the Triumph of the Cross. In some parts of the Anglican Communion the feast is called Holy Cross Day, a name also used by Lutherans. The celebration is also sometimes called Holy Rood Day, or by the historical names Roodmas or Crouchmas.
The Feast of the Exaltation of the Holy Cross, celebrated every year on 14 September, recalls three events:
The finding of the True Cross by Saint Helena.
The dedication of churches built by Emperor Constantine on the site of the Holy Sepulchre and Mount Calvary.
The elevation of the True Cross at Hagia Sophia in Constantinople in AD 629 by the Byzantine emperor Heraclius, after it had fallen into the hands of the Persian Emperor Chosroes II in the AD 614 Sasanian conquest of Jerusalem.
Under Emperor Constantine, around AD 327, Bishop Macarius of Jerusalem caused excavations to be made in order to ascertain the location of Calvary as well as that of the Holy Sepulchre. It was in the course of these excavations that the wood of the cross was recovered. It was determined by Macarius to be authentic (the crosses of the two thieves were also recovered) and for it Constantine built the Basilica of the Holy Sepulchre. Subsequently, pieces of the True Cross relic were distributed across the empire and by the turn of the 5th century were venerated as far away as Italy.
The Ancient Georgian Iadgari (Chantbook) bears witness to the celebration of the Exaltation of the Cross in Jerusalem before the middle of the 6th century. In the west before the end of the seventh century the feast was mainly observed in Rome. However, the earliest recorded commemoration of 14 September as the feast day on a Western calendar is from the 7th century AD.
In the Gallican usage, beginning about the seventh century, the Feast of the Cross was celebrated on 3 May, and called "Crouchmas" (for "Cross Mass" or "Mass Of The Cross") or "Roodmas". When the Gallican and Roman practices were combined, the September date was assigned to commemorating the rescue of the cross from the Sassanid Persians, and the May date was kept as the Finding of the Holy Cross or Invention of the True Cross to commemorate the finding. ("Invention" is a rendering of the Latin term inventio meaning "discovery".) Pope John XXIII removed this feast in 1960, so that the General Roman Calendar now celebrates both the finding and the exaltation of the Holy Cross on 14 September, although various places in Latin America, Mexico, and the Philippines still celebrate the feast of the finding on 3 May. Communities which celebrate the Extraordinary Form of the Roman Rite also observe the feast of the finding of the Holy Cross on 3 May.
The Second Council of Nicæa of 787, drew the distinction between veneration of the cross and worship or latria, "which, according to the teaching of the faith, belongs to the Divine nature alone." Petavius noted that this cult must be considered as not belonging to the substance of religion, but as being one of the things not absolutely necessary to salvation. Thus, the honor paid to the image passes to the prototype; and he who adores the image, adores the person whom it represents.
According to Christian tradition, the True Cross was discovered in 326 by Saint Helena, the mother of the Roman Emperor Constantine the Great, during a pilgrimage she made to Jerusalem. The Church of the Holy Sepulchre was then built at the site of the discovery, by order of Helena and Constantine. The church was dedicated nine years later, with a portion of the cross. One-third remained in Jerusalem, one-third was brought to Rome and deposited in the Sessorian basilica Santa Croce in Gerusalemme (Holy Cross in Jerusalem), and one-third was taken to Constantinople to make the city impregnable.
The date of the feast marks the dedication of the Church of the Holy Sepulchre in 335. This was a two-day festival: although the actual consecration of the church was on 13 September, the cross itself was brought outside the church on 14 September so that the clergy and faithful could pray before the True Cross, and all could come forward to venerate it.
Historically in Western Christianity, the Wednesday, Friday, and Saturday of the calendar week after the one in which the feast day occurs are designated as one of each year's four sets of Ember days. Until 1969, these ember days were a part of the liturgical calendar of the Roman Catholic Church. Organization of these celebrations in the ordinary form is now left to the decision of episcopal conferences in view of local conditions and customs. The ember days are still observed in the calendar of the Roman Rite's Extraordinary Form, the Anglican Ordinariate, and Western Orthodoxy.
Red is the usual liturgical color in churches that follow such traditions.
In Western Christianity, red vestments are worn at church services conducted on this day.
The lectionaries of the Church of England (and other Anglican churches) and Western Rite Orthodoxy also stipulate red as the liturgical color for 'Holy Cross Day'.
In Eastern Orthodox Churches that use various liturgical colors, red vestments are also worn. Yet in these Orthodox churches, the wearing of red continues for a week after the feast.
